Synopsis A more active monsoon pattern will occur through
this weekend with temperatures returning to near or slightly below
normal. High pressure returning for the first half of next week will
usher in drier conditions once again along with above average
temperatures.

Discussion Skies are clear for the time being across southeast
arizona as indicated by visible and IR satellite imagery. Surface
observations indicate moisture continues to return to the region
with dewpoints in the low and mid 60's in many valley locations. The
added moisture is keeping temperatures a few degrees cooler compared
to 24 hours ago, and our highs later this afternoon should follow
suit, even though values will still peak above normal. Pwat on the
22 12z ktwc RAOB was just under 1 inch, but we have more instability
to work with today with mu-cape around 1200 j kg and a LI of -3.

Many cam solutions including the u of a wrfnam, wrfgfs and 4km nam
nest were fairly consistent with hitting cochise, santa cruz and
southern pima counties pretty hard this afternoon with convection
and heavy rainfall. Expect storms to initiate over terrain first
before moving into the valleys with colliding outflows and
subsequent storm development to be the story. With 1800 j kg of
dcape from the sounding this morning, we expect the primary threat
today to be gusty winds with a few strong or even severe storms.

With how hot and dry its been the last several days, expect outflows
to kick up some dust across mainly pima county as storms move
westward, with reduced visibility at times. All this said, made some
short term tweaks to the grids regarding pops and qpfs as well as
added blowing dust to the weather grids. For more information on the
forecast into this weekend and beyond, please refer to the previous
discussion.

Aviation Valid through 23 18z.

Few-sct clouds at 10k-14k ft msl west of ktus and sct-bkn clouds
south and east of ktus through the forecast period. Isolated to
scattered tsra shra will develop early this afternoon primarily from
ktus kols eastward with brief MVFR vsby CIGS possible, particularly
near terrain. Precip decreasing this evening though a few -shra
could linger overnight near the international border including
kdug kols. Gusty outflow winds are possible near tsra shra up to
around 40 kts. Otherwise, sfc wind mainly swly to wly around 7-14
kts becoming primarily sly overnight. Aviation discussion not
updated for TAF amendments.

Fire weather Mainly afternoon and evening thunderstorm chances
increase starting today to include much of southeast arizona and
will continue into the weekend before drier weather returns early
next week. The return of deeper monsoonal moisture will allow
temperatures to fall back to near seasonal levels by Friday which
will remain through the weekend before warmer temperatures return
next week. Any thunderstorms that do develop may produce gusty and
erratic outflow winds. Otherwise, 20-ft winds will generally follow
normal diurnal trends at less than 15 mph.

Prev discussion Latest models continued to advertise a more
activate thunderstorm pattern developing through this coming
weekend. Deep moisture pooled south of the region was progged to
spread northward into southeast arizona by late Friday. This
increase in moisture will signal an upswing in daily showers and
thunderstorms, especially on Friday and Saturday. This more active
thunderstorm pattern will be brief, as models showed another dry
spell for early next week along with a return of very hot
temperatures. In the meantime, the increase in moisture and
subsequent thunderstorms will help cool daytime temperatures to near
or slightly below normal.

Twc watches warnings advisories None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
